Letters Patent No. 93,723, dated August 11, 1869.

IMPROVEMENT 1N rum-BRUSHES. y

The Schedulexefervred to in thesev Letters Patent: and making part of the same.

T0 all 'whom it may concern Be it known that I, JOHNS D. KUNKEL, of Cincinnati, county of Hamilton, StateA of Ohio,- have invented acer-tain new and' useful Improvement in the Construction of Brushes for Cleaning Flues: and Ido liereby declare the following to be a sufficiently full, clear, and exact description thereof, to enable one skilled in the art to which my invention appertains, to make and use it, reference being had to the accompanying drawings, making part of this speccation.

My invention consists of certain devices by which the bristles, or suitable jute material, of the brush are vfolded and arranged in complete, unbroken, circular layers, and properly secured.

In the accompanying drawing- Figure l is a perspective view, exhibiting the device ou which the circular layer fbristles is formed.

Figure 2 is'a view of one of the `heads or plates used for connecting the layers together. f

Figure 3 is an axial section of a brush, composed of four layers of folded bristles, or suitable jutematerial,

properly secured together.'y

The bristles, or suitable jute material, are `folded upon rings A of metal wire, any number of which may be used in theformation of the brush, one ring to each 'folded layer.

B B are wooden heads, between which the' layers of bristles, or suitable jute material, are secured.

Each head is composed of two pieces secured to-l hand. v

gether, the grain of one being at right angles to the other, to prevent splitting.

4 The heads B B are secured bolts, C, which are arranged in a circle, to t closely the interior circle of the folded bristles, or suitable jute material.

It will be seen that when the bristles, or suitable jute material, are folded and arranged on the rings A,

eachlayerl is' a complete circle of equal thickness.

I am aware that other devices have been used, in which the bristles, or suitable jute material, are arrangedin radial tufts, folded through apertures in plates or boards, but it is impossible, with this manner of construction, to make' a brush oi' equal thickness throughout the circle.

This device can be'applied to all other kinds` ofA brushes, the rings A being varied in shape to suit any convenient form of brush.

I claim herein as new, and of my invention-Q The construction and combination of rings A, heads B B', bolts G, and manilla grass or jute, as shown and described.

In testimony of which invention, I hereunto set iny JNO. D.' KUNKEL.
